Subject: [PATCH RFC 05/21] NFSD: Adjust cb_shutdown tracepoint
Date: Mon, 10 May 2021 11:52:08 -0400	[thread overview]
Message-ID: <162066192841.94415.605232504487207748.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <162066179690.94415.203187037032448300.stgit@klimt.1015granger.net>

Show when the upper layer requested a shutdown. RPC tracepoints can
already show when rpc_shutdown_client() is called.
